Rachel has always been open-minded about her step-son Robert's love of bondage. At Christmas she presents him with a very special gift: two sexy neighborhood women lying tied up and helpless on the living room floor. Next to them are a couple of big vibrators. The young is delighted with what his step-mom has gotten him. Taking up one of the vibrators, he starts rubbing its over the pussy of the nearest woman. A bikini-clad Rachel does the same with her companion. Soon the room is filled with feminine squeals, giggles, and cries of orgasm.
